Hello
We have designed camera gymbal.  Any servos are not for this task, they are shaking, and not accurate. You have to use backlash free mechanisms, H-bridge for motors, and place gyros on camera. Our  device has this conditions, but works not quite well yet.
About Kalman, try avr_imu: http://forum.sparkfun.com/viewtopic.php?t=6186&postdays=0&postorder=asc&highlight=kalman&start=15
I tested it, works good.

Hello,
 
 
I'm designing an IMU to stabilize a video gimbal for small UAV's. I'm using gyros and accel from Sparkfun and super fast digital servos from MKS. It will have a tilt of 100 degrees and a continuous 360 degrees of pan. I will use amodified digital servo from MKS and an encoder.
 
At first tests, I will use Arduino board. But when success I intend to pass to the paparazzi board. So, I can connect the two paparazzi boards with SPI bus. After the IMU will stabilize the video system and the aircraft too.
 
I'm facing a litle problems with the inicial C code with the kalman filter. I think the gyro integrate is wrong.
 
Anyone have experience in IMU's and kalman filtering? We need some help with our code.

Best regards
Rui Costa
